What are the key features of SFM-105-L2-STL-D-K-TR?
- 10-position dual-row socket strip at 0.050" pitch with short-tail (STL) contacts for improved solder joint coplanarity in SMT assembly
- High-reliability contact design rated for hundreds of mating cycles, maintaining low contact resistance across all 10 positions
- Tape-and-reel packaging enabling automated pick-and-place placement for consistent SMT assembly in volume production
What is SFM-105-L2-STL-D-K-TR used for?
The SFM-105-L2-STL-D-K-TR suits compact embedded modules, sensor daughter cards, and small form-factor SOM expansions requiring a 10-position fine-pitch socket interface. Its 0.050" pitch dual-row layout concentrates 10 contacts into a minimal PCB footprint, making it ideal for wearable electronics, IoT sensor nodes, and miniaturized industrial control boards where board area is critical. The short-tail contact variant ensures reliable solder joints during reflow processing of thin or flexible PCB substrates.

Frequently Asked Questions
For a miniaturized IoT sensor module, how does the 0.050" pitch of the SFM-105-L2-STL-D-K-TR reduce the PCB footprint compared to a 0.100" pitch 10-position socket?
At 0.050" (1.27 mm) pitch, the SFM-105-L2-STL-D-K-TR places 10 contacts in a body length of approximately 5.08 mm for the 5-position-per-row dual-row layout, roughly half the length of an equivalent 0.100" pitch socket. This space saving is significant on IoT sensor nodes where the total board area may be only 20 mm × 30 mm, and every square millimeter freed by the connector reduces enclosure size.
What is the benefit of the short-tail (STL) contact on the SFM-105-L2-STL-D-K-TR when assembling thin flexible PCB substrates?
The short-tail contact minimizes the distance from the connector seating plane to the solder termination point, reducing the mechanical moment arm that would otherwise stress a thin or flexible PCB during thermal cycling. For substrates below 0.8 mm thickness common in wearable and compact embedded designs, the STL contact lowers the risk of PCB warping and delamination at the solder joint over the rated operating temperature range.
When would an engineer select SFM-105-L2-STL-D-K-TR over a standard 10-pin FFC/FPC connector for a daughter card interface?
SFM-105-L2-STL-D-K-TR is preferred when the daughter card is a rigid PCB rather than a flat flexible cable, since the socket strip mates directly to a 0.050" pitch header with defined normal force across all 10 contacts. FFC/FPC connectors require a flexible cable and a separate ZIF or LIF socket mechanism, adding approximately 2 mm to 4 mm of connector stack height and an additional cable component to the BOM.
